The German tactician believes he has been unable to focus on his team’s tactics due to the fitness of some of his players at the start of the campaign, suggesting they were badly out of shape.

Klopp believes his side will stay up this season after a shocking first half of the campaign, and has admitted he doesn’t care about progressing in the Champions League or about missing out on the competition next season.

“I’m not at all interested in the Champions League,” Klopp is quoted as saying.

“As things stand right now, I would have no problem just staying up and then being able to train a lot next season.

“If there are any of my players who would rather move somewhere else just because they will play one year without the Champions League, then clearly I’ve judged them completely wrong.

“We’ve got 17 games and we will do it. That’s a hell of a lot.

“We’ve now been able to work on so many things that we had no time to go over even once in the summer. We weren’t able to work tactically one single time because the lads first had to get into decent shape.”

Klopp has previously let Dortmund to two league titles and the final of the Champions League, and has been linked with the manager’s job at big clubs such as Arsenal and Liverpool.
